CN4093 Application Guide for N/OS 8.4
 Chapter 6, "802.1X Port‐Based Network Access Control," describes how to
authenticate devices attached to a LAN port that has point‐to‐point connection
characteristics. This feature prevents access to ports that fail authentication and
authorization and provides security to ports of the CN4093 that connect to blade
servers.
 Chapter 7, "Access Control Lists," describes how to use filters to permit or deny
specific types of traffic, based on a variety of source, destination, and packet
attributes.
 Chapter 8, "VLANs," describes how to configure Virtual Local Area Networks
(VLANs) for creating separate network segments, including how to use VLAN
tagging for devices that use multiple VLANs. This chapter also describes
Protocol‐based VLANs, and Private VLANs.
 Chapter 9, "Ports and Link Aggregation (LAG)," describes how to group
multiple physical ports together to aggregate the bandwidth between
large‐scale network devices.
 Chapter 10, "Spanning Tree Protocols," discusses how Spanning Tree Protocol
(STP) configures the network so that the switch selects the most efficient path
when multiple paths exist. Also includes the Rapid Spanning Tree Protocol
(RSTP), Per‐VLAN Rapid Spanning Tree Plus (PVRST+), and Multiple Spanning
Tree Protocol (MSTP) extensions to STP.
 Chapter 11, "Virtual Link Aggregation Groups," describes using Virtual Link
Aggregation Groups (vLAG) to form LAGs spanning multiple vLAG‐capable
aggregator switches.
 Chapter 12, "Quality of Service," discusses Quality of Service (QoS) features,
including IP filtering using Access Control Lists (ACLs), Differentiated Services,
and IEEE 802.1p priority values.
 Chapter 13, "Stacking," describes how to implement the stacking feature in the
Lenovo Flex System Fabric CN4093 10 Gb Converged Scalable Switch.
Chapter 14, "Virtualization," provides an overview of allocating resources

based on the logical needs of the data center, rather than on the strict, physical
nature of components.
 Chapter 15, "Virtual NICs," discusses using virtual NIC (vNIC) technology to
divide NICs into multiple logical, independent instances.
 Chapter 16, "VMready," discusses virtual machine (VM) support on the
CN4093.
Chapter 17, "FCoE and CEE," discusses using various Converged Enhanced

Ethernet (CEE) features such as Priority‐based Flow Control (PFC), Enhanced
Transmission Selection (ETS) and FIP Snooping for solutions such as Fibre
Channel over Ethernet (FCoE).
 Chapter 18, "Fibre Channel," describes how to configure the CN4093 for use
with Fibre Channel networks.
